T0 @ZZ whom it may concern.-

PITTLER, a subject of the German Emperor, residing at Leipsic-Gohlis, Germany, have invented certain new and usefullmprovements in Machines for Making Cigars; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as .Y

will enable others skilled in the art to which it appert-ains to make and use the saine.

This invention relates to a machine for manufacturing cigars of compressed tobacco having longitudinal channels; and its object is to provide an efficient and satisfactory mechanism for making cigars from tobacco pressed previouslyin a preferably cylindrical form adaptedto the machine. The machine has a piston pressing the tobacco into a pressing-chamber and from this through one or several channels in which one or more wires are arranged in such a manner that the ends lie freely in these channels, so that the tobacco is pressed aroundthese wires. The tobacco is in this manner formed to a long rod having longitudinal draft channels corresponding to the said wires, and from this rod the cigars are cut off by a suit-able mechan- In the drawings, Figure 1 is a longitudinal vertical section through a machine of this kind having a piston which is actuated upon by hydraulic pressure. Fig. 2 is a horizontal section on line AB of Fig. 1. Fig. 3 is a longitudinal section showing, on a larger scale, the fastening of the Wires forming the draftchannels. Fig. 4 is a cross-section on line C D of Fig. 3. Fig. 5 is a cross-section, on a larger scale, showing the mold and the arrangement of several wires in the same. Fig. '6 is a View of that side of the mold from which the tobacco is fed to the mold. Fig. 7 is a cross-section through the mold on line E F of Fig. 5. Figs. 8 and 9 showa pressed cigar in longitudinal and in cross section o n a larger scale. Figs. 10 and 1l show modifications in the fastening of several Wires by means of a cross-bar. Fig. 12 is a longitudinal section through a machine, the piston of which is operated by worm-gearings. Fig. 13 is a crosssection on line Gr H of Fig. 12.

In referring iirst to the construction in Figs. 1 and 2, the machine has a plunger b, a pis- I ton b', a pressing-chamber c, with a prolonga- Be it known that I, .IULIU's WILHELM VON tion c', and a block lo', containing the molds for forming the cigars.- The bloclokk 7c, which Vis shown in Figs. 3 and et on a larger scale,

has several molds h, which are enlarged conically to that side Where they are connected to the pressing-chamber cp InI the conical enlargement the conescare inserted, in which one, Fig. 3, or several, Fig. 5, wires g are arranged,.the ends of which lie freely in the molds h. On the periphery of the cones c several grooves or channels j', Figs. 3 to 6, are arranged, forming the communication between the pressing-chamber c and the molds /L of the block k, through which channels the tobacco is fed forward, so that it surrounds the wires g. It is necessary that the Wires g are not touched by the pressing-piston b'.

Instead 0f the cones e a cross-bar e', Figs. 10 and 1l, can be arranged for fastening the Wires or any other suitable mechanism.

The working of the machine is as follows: The tobacco previously pressed into a cylindrical form (t) of a certain length is put through the opening CZ on the prolongation c of the pressing-chamber in the position shown in Figs. 1 and 2, in which the plunger b and piston b are in the extreme rearward position. Then by pressure the plunger' b is pressed forward, so that it presses the bodyt of tobacco into the pressing-chamber c against the block la. The tobacco is forwarded through the openings f, which are partly in the cones e and partly in the block lo, into the molds h around the Wires g, so that in each mold k a tobacco-rod is formed having the diameter of the mold h and such a number of channels 2, Figs. 8 and 9, as-there are Wires g in the mold. The screw-threaded sleevesz' form adjustable abutments for the molds, so that the position Vof the latter can be adjusted. Tubes L may be attached to the end of the molds, so that the newly-formed rod of tobacco shall not be permitted to bend.

In Figs. 12 and 13 a modification of the inachine is shown, in which the piston is not actuated upon by a hydraulic pressure, but by means of a belt.

The pulleys m and m' for right and left rotation and the idle pulley fm2 are arranged on the main shaft n. The rotation of the latter is transmitted through the Worm 0 to the IOO Worm-Wheel p, which in this case is formed as a screw-nut. The screwb is moved to and fro by the right or left hand rotation of the Worm o. For preventing the rotation of the screw-bolt b bars r and r are fastened to the frame a in such a manner that they engage With a corresponding longitudinal channel of the screw Z). The machine here shown is double, Workin g in such a manner that the screw b has a piston b on both ends. The previously-pressed tobacco t is fed to the prolongation c of the pressing-chamber c in the same manner as previously described and is pressed by the piston b into the pressing-chamber c and the molds h of the block 7c. The Working of this machine is the same as that of the machine actuated upon by hydraulic pressure.

Having now particularly described my invention, what I claim, and desire to secure by Letters Patent, is-` 1. In a machine for forming cigars, the combination of a pressing-chamber, a piston or plunger Working therein, a mold, and a conical head resting in the end of the mold adjacent to the pressing-chamber, said mold communicating with the pressing-chamber through channels formed on the surface of said conical head, and wires connected to said head and extended into the mold, subst-antially as described.

2. In a machine for forming cigars with longitudinal draft-channels, the combination of a pressing-chamber, a piston or plunger Working therein, a mold connected with said pressing-chamber through a conical enlargement,

nels in the Wall of the mold to form vpassages communicating with said pressing-chamber and mold, and Wires connected to said head and extending into the mold, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
